hello Please provide users with 3D exported CAD file of mini2440 PCB It easily exported using 'save as' command of altium/protel thanks
.step file of mini2440 (3D exported CAD file)
Are you sure the design is done in Altium and that they actually used 3D models in doing so? The schematics indicate that it is Altium but no way to know which version or if they used the 3D capabiliy.
Usually, parts/components in the libraries have 3D model by default. Even, you can simply define a 'mechanical layer' as '3D body' of custom design parts/components in your PCB Library. Various versions of PCB files (even between various applications/products) are imported as new files. Only, PCB file of mini2440 is in demand for generating a 3D CAD file. Because of privacy/commercial considerations (and usually by default in .step files), the track layers are omitted during generation of 3D body. A. Rostamzadeh www.instrumentalanalysis.com
